The Business Plan for Establishing of Small Company
Valenta, Roman ; MBA, Michal Bábíček, (referee) ; Koráb, Vojtěch (advisor)
This diploma thesis deals with the creation of a business plan. This plan is concerned with the startup of an online store which specializes in speakers, headphones and accessories. The thesis explores business plan theory and utilizes the SLEPTE, SWOT and McKinsey 7S analyses complemented by an analysis of my own research. Based on the above mentioned information, the business plan itself is drawn up.

Design of modern speaker body with usage of new technology
Kůst, Martin ; Prokop, Aleš (referee) ; Řehák, Kamil (advisor)
This diploma thesis deals with the analysis and design optimization of a speaker cabinet (enclosure) produced by the additive technology of 3D sand printing. The introductory part is devoted to the theory, both in the field of noise, vibration and the method of their calculations, as well as the theory of speakers and their systems. Numerical and experimental modal analysis is performed, which were compared to determine the mechanical properties of the new material, including material damping. This is followed by experimental and numerical harmonic analysis, with output in the form of a numerical model describing the behaviour of the structure during its excitation. The data are compared with a modal analysis of the internal acoustic space and the critical shapes and their frequencies are determined. At the end of the work, construction modifications are proposed to increase the rigidity of enclosures, the influence of which is evaluated on the created numerical models.

Up-firing loudspeakers for 3D Audio
Pešek, Marko ; Schimmel, Jiří (referee) ; Balík, Miroslav (advisor)
This bachelor theses dealing with study multichannel 3d audioformat Dolby Atmos and parameters of up–firing loudspeakers, which assures overhead audiosignal reproduction coming towards hearer. According to the knowledge is made proposal of up–firing loudspeakers, fabrication and measurement their properties.

Design of sound reinforcement system
Košarišťan, Miroslav ; Hruboš, Zdeněk (referee) ; Brančík, Lubomír (advisor)
This Master´s thesis deals with sound apparatus. The first part is a theoretical explanation of the main part of the equipment, such as microphones, amplifiers, proofreaders, switches and speakers. Another section is devoted to the design itself, starting with the block diagram which is followed by the design of single important parts. These are made as PCB. For select-ed diagrams there is an example of PSpice program simulations and the measurement of important characteristics. The essential part of the work also addresses constructional pro-cessing of apparatus. At the end of this thesis some examples of the PCB are introduced.

The Design Methods of Equipments for Audio
Kondler, Radim ; Vrba, Kamil (referee) ; Mišurec, Jiří (advisor)
The work is focused on equipment used in audio, such as a loudspeaker crossovers, amplifiers and preamplifiers. There are theoretically described loudspeaker crossovers, their parameters, types of structures derived from the frequency filters with their parameters. Further deals about audio amplifiers and both voltage and power, their theories, parameters, and distribution.

From sea to summit
Staniczek, Jan ; Solčáni, Ján (referee) ; Šrámek, Jan (advisor)
In my thesis I try to convey strange feelings that are inherently connected with post-anthropocentric, ecological thinking of inter-object coexistence, through an installation of a series of clay speakers. From a theoretical point of view, I rely upon Fisher's conception of weird and Morton's conception of dark ecology, in which I found a surprisingly apt articulation of my own feelings, as well as inspiration for further thinking and imagination. The main points in the otherwise difficult to define direction of my work are the planes of blurring borders, ephemerality of experience and intimate contact with otherness.

Database of recordings for detection of voice activity
Pelikán, Pavel ; Hudec, Antonín (referee) ; Míča, Ivan (advisor)
This thesis deals with voice activity detection (VAD) and requirements for creating a speech database. One of the existing tools for marking recordings was chosen. On the basis of the gained knowledge, database of isolated words, sentences, text and spontaneous speech was created. The practical part consists of a detailed description of database and mark creation. Furthermore, the thesis deals with the conversion of marks into Matlab. There are also some auxiliary scripts for operations with marks. Prepared and a database was created in an anechoic chamber and includes recordings from 16 speakers.
